LED spots in insulated ceiling - topic fire protection

Hello everyone,

I have been racking my brains for weeks.
We are building a wooden house and have wood fiber insulation and a vapor barrier on the ground floor under the roof terrace.
Below that, we have 6cm of counter battens and on top of that comes 1cm of Fermacell.
So, 7cm from the bottom edge of the Fermacell to the underside of the vapor barrier.

The vapor barrier is well tensioned, so that with some pressure you could get out a maximum of one cm... so 7-8cm maximum height.

We plan to install GU10 LED spotlights, but the height including the socket is roughly 7cm.
Which Kaiser box would I have to use so I don't set anything on fire in the ceiling?
There are two variants: ThermoX LED and ThermoX, with ThermoX LED stating "not suitable for NV and HV spotlights." Stupid question, but what's left then?

In any case, I would need your opinion and suggestions. How do I install the adjustable GU10 LED spots in the ceiling without setting the place on fire?

Regards
Tito

Hello Tito,

we used Kaiser 9300-02 Thermo-X.

Hmm, they are 90mm deep. That is too tight for me.
Do you have halogen or LED?

We have LED spots. I also wanted to take the ones you wrote about at first, but according to the provider, they wouldn’t have held up with us and we have similar ceilings. I don’t think you can use those either.
Just get advice from Voltus. The customer service helps immediately and competently.
